rules of online form of Fyziklani

Rules are also available in PDF.



  • If a team wants to participate, it must register through
  • By registering for the competition, each team agrees to follow the Rules of Conduct and these Competition Rules, and confirms they have made themselves acquainted with them.
  • A team consists of 1-5 members.
  • All members of the team must be students of a school equivalent to high school (pre-university education) or lower.
  • A team must consist of members belonging to at most two schools.
  • Students of a single school can compete at most in four distinct teams. In the case of unfilled places or other similar conditions, the organisers reserve the right to make an exception to this rule.
  • Each contestant can compete in one category only and be a member of only one team (see Designation into Categories).
  • The name of a team can't spread political or religious views, can't be rude or insulting, or be in any other way inappropriate. The chief organiser has a right to change the name of such a team, to censor it or to disqualify the team completely.
  • By registering in the competition, you agree with publishing the results of your team in the form of basic information (your name, surname, category, school and points) in the results table on the website, handbooks and yearbooks of FYKOS.

Designation into Categories 

  • Teams compete in three categories, to which they are placed based on the following algorithm.
  • Each player has a coefficient based on the expected year of graduation. If a player studies the last year of secondary education, he gets a coefficient of 4. If he studies the penultimate year, he gets a coefficient of 3 and so on. A minimum possible coefficient is 0.
  • The coefficient of a team is calculated as the arithmetic mean of the coefficients of individual members (they are added together and divided by the number of members).
  • The team is assigned the lowest category whose conditions it satisfies:
    • category A: team coefficient ≤ 4,
    • category B: team coefficient ≤ 3 and at most two members have a coefficient 4,
    • category C: team coefficient ≤ 2, no member has a coefficient 4 and at most two members have a coefficient 3.
  • A team can compete in category A even if its coefficient places it into a lower category if they choose to do so during the registration.
  • All categories share the same set of problems.
  • Each category of the competition has a separate list of results.


Competition environment

  • The competition is online in a competition environment, which you can access from the Fyziklani website. The link to the competition environment will be also sent by email to the contestants.
  • The teams log in with their team password, which they create at the registration.
  • Problems will be published in the form of PDF files in the competition environment after the beginning of the competition.
  • Teams send the results directly via the competition environment. Results sent by other means (email, etc.) will not be accepted.
  • Official announcements from the organisers will be communicated via the online board, in exceptional cases by email. The teams are required to watch the online board.
  • During the competition, the up-to-date scores of all teams are accessible. These are hidden 30 minutes before the competition finishes.

The competition system and awarding of points 

  • The competition lasts 3 hours.
  • The teams solve the problems. For every correct answer to a problem the team receives a new problem, unless the solved problem is the last problem of a series (see below).
  • The problems are lined up in series with a set number of problems. Each of the series is published at a particular time (not necessarily at the beginning of the competition).
  • Lengths of the series (total number of problems), their starting times and the number of problems the team receives when the series is started can be found in a schedule which will be published with the closure of registrations latest. 
  • All problems are marked according to the number of submitted answers: the first answer is correct - 5 points; the second answer is correct - 3 points; the third answer is correct - 2 points; the fourth or later answer is correct - 1 point.
  • If a team finishes a series, they get bonus points - equal to the number of correctly answered problems in that series (i.e. skipped problems do not count, see below).
  • The aim of the team is to receive as many points as possible.
  • If the team answers some problem incorrectly, they will not be allowed to submit any answer for 1 minute.
  • If there is a serious issue discovered with one of the problems during the competition, organisers reserve the right to modify the problem or to remove the problem from the competition completely, excluding any right to compensation for any of the teams.
  • During the competition, all the participants are allowed to communicate only with the members of their own team or with the organisers. Any interaction with teachers, other teams, etc. is strictly forbidden.
  • The teams need computer(s) or similar equipment with access to the internet.  Furthermore, teams are permitted to use calculators and writing or drafting supplies.
  • Teams are permitted to use the internet and any literature as a source of information.
  • The competition is based on fair-play. The competition is monitored in order to prevent cheating.
  • In the official communication channel of the competition, it is forbidden to use abusive language, give hints to other teams or discuss the solutions.

Bonus cards

  • At the beginning of the competition, all teams receive 6 bonus cards. Each of the cards possesses some special power and each of them can be used only once. The cards are the following:
    • Skip the problems - the team can skip an arbitrary number of problems they are currently solving.
    • Reset points - the marking scheme of the problem is reset, the team can get 5 points for a correct answer again.
    • Double points - if the first answer submitted after using this card is correct, the team receives doubled points for the answer.
    • Add one problem from a series - the next problem from a chosen series is revealed, the team can therefore solve more problems from the series at once.
    • Hint (only some problems) - the team can read a hint to the solution (only some of the problems have hints).
    • Multiple choice - the team receives 4 possible answers to the question, one of them is correct

Format of the results

  • The answer to every problem is always a number.
  • The number of significant figures and the units of the answer are always written in the problem task.
  • There will be a table of constants published. It is recommended to use these values in order to get the correct answers in the tolerance interval.

Conclusion of the Competition and Announcement of Winners

  • The competition ends 3 hours after its start.
  • Winning team is the team with the highest number of points.
  • If two or more teams have the same point score, the auxiliary criteria are as follows: higher average score per problem; higher number 5-points answers; higher number of 3-points answers; lower team coefficient; earlier date and time of registration. The bonus points for closing a series and points for using the card „Double points“ are not considered.
